Birth of Our Universe

So lets talk about the birth of our universe. How was it formed? By Big-bang. Now what is this Big-bang? Why it happened? How it happened? Let's find out.

BIG BANG



According to our knowledge and accuracy, our universe was formed some 13.7 billion years ago in a massive explosion which burst out everything, every single element present in our universe that we know as Big-bang.

So what caused this big-bang? Currently most scientists agree on this hypothesis that big-bang was caused by an infinitely small particle of infinite density that was so much unstable that it released it's energy in this massive explosion. This explosion released so much energy that elements fused and disintegrated to form new elements creating everything present around us.

Now how this tiny energetic particle formed? Nobody knows. This is the point where human imagination stops working. This is why scientists say that time started ticking at the instant of big-bang. So, how we know about that extremely tiny energetic particle? Again this concept is totally hypothetical. From decades scientists are locating some galaxies far distant from us and what they found is that our universe is expanding. All the galaxies are going far from each other as if they started from a same point. So if we go back in time it may be possible that all these galaxies fuse together and create a body of huge mass whose mass goes on increasing and then because of its huge gravitational force the mass collapses into an infinitely small and infinitely dense particle which later caused the big-bang.
